Important Information

Fire and Shock Precautions

• Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your

projector. Allow at least 4 inches (10cm) of space between your projector and a wall.

• Do not try to touch the ventilation outlet on the left front (when seen from the front) as it can become heated while

the projector is turned on and immediately after the projector is turned off.

• Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to

retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver

into your projector. If something should fall into your projector, disconnect it immediately and have the object removed

by a qualified service personnel.

• Do not place any objects on top of the projector.

• Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.

• The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply

fits this requirement before attempting to use your projector.

• Do not look into the lens while the projector is on. Serious damage to your eyes could result.

• Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the

lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can cause

unpredictable outcome such as fire or injury to the eyes.

• Do not cover the lens with the black lens cap or equivalent while the projector is on. Doing so can lead to melting of

the cap and possibly burning your hands due to the heat emitted from the light output.

• Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust vent.

Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the light

output and exhaust.

• Handle the power cable carefully. A damaged or frayed power cable can cause electric shock or fire.

- Do not use any power cables than the supplied one.

- Do not bend or tug the power cable excessively.

- Do not place the power cable under the projector, or any heavy object.

- Do not cover the power cable with other soft materials such as rugs.

- Do not heat the power cable.

- Do not handle the power plug with wet hands.

•Turn off the projector, unplug the power cable and have the projector serviced by a qualified service personnel

under the following conditions:

- When the power cable or plug is damaged or frayed.

- If liquid has been spilled into the projector, or if it has been exposed to rain or water.

- If the projector does not operate normally when you follow the instructions described in this user's manual.

- If the projector has been dropped or the cabinet has been damaged.

- If the projector exhibits a distinct change in performance, indicating a need for service.

• Disconnect the power cable and any other cables before carrying the projector.

•Turn off the projector and unplug the power cable before cleaning the cabinet or replacing the lamp.

•Turn off the projector and unplug the power cable if the projector is not to be used for an extended period of time.

Place the projector in a horizontal position

The tilt angle of the projector should not exceed 10 degrees, nor should the projector be installed in any way other

than the desktop and ceiling mount, otherwise lamp life could decrease dramatically.

10

iv

CAUTION

• Do not use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or

hanging on the wall can cause damage to the projector.

• Do not send the projector in the soft case by parcel delivery service or cargo shipment. The projector inside

the soft case could be damaged.

• When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle

to the projector cabinet are tight.

Insufficient tightening of the two screws could result in the projector falling and causing injury.

• Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select

[Setup] → [Options] → [Fan Mode] → [High].)

• Do not turn off the AC power by pressing the main power switch or by unplugging the power cable when the

projector is powered on.

• Do not turn off the AC power for 60 seconds after the lamp is turned on and while the POWER indicator is blinking

green. Doing so could cause premature lamp failure.

Remote Control Precautions

• Handle the remote control carefully.

• If the remote control gets wet, wipe it dry immediately.

•Avoid excessive heat and humidity.

• Do not heat, take apart, or throw batteries into fire.

• If you will not be using the remote control for a long time, remove the batteries.

• Ensure that you have the batteries’ polarity (+/-) aligned correctly.

• Do not use new and old batteries together, or use different types of batteries together.

• Dispose of used batteries according to your local regulations.

Lamp Replacement

•To replace the lamp, follow all instructions provided on page 52.

• Be sure to replace the lamp when the message [The lamp has reached the end of its usable life. Please

replace the lamp.] appears. If you continue to use the lamp after the lamp has reached the end of its usable

life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as

the pieces of glass may cause injury.

If this happens, contact your dealer for lamp replacement.

A Lamp Characteristic

The projector has a high-pressure mercury lamp as a light source.

A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on

and off will increase the possibility of its lower brightness.

CAUTION:

When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass

fragments could fall if the lamp has been burned out.

This section describes how to set up your projector and how to connect video and audio sources.

Your projector is simple to set up and use. But before you get started, you must first:

1 Set up a screen and the projector.

2 Connect your computer or video equipment

to the projector.

(→ page 13,14,15,16,17,18)

3 Connect the supplied power cable.

(→ page 19)

NOTE: Ensure that the power cable and any

other cables are disconnected before moving

the projector. When moving the projector or

when it is not in use, cover the lens with the

lens cap.

 Setting Up the Screen and the Projector

Selecting a Location (VT695)

The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is

approximately 21" (0.53 m) measured diagonally when the projector is roughly 38 inches (1.0 m) from the wall or

screen. The largest the image can be is 300" (7.6 m) when the projector is about 389 inches (9.9 m) from the wall or

screen.

2. Installation and Connections

WARNING

* Installing your projector on the ceiling must be done

by a qualified technician. Contact your NEC dealer

for more information.

* Do not attempt to install the projector yourself.

• Only use your projector on a solid, level surface. If the

projector falls to the ground, you can be injured and

the projector severely damaged.

• Do not use the projector where temperatures vary

greatly. The projector must be used at temperatures

between 41˚F (5˚C) and 104˚F (40˚C) (Eco mode

selected automatically at 95˚F to 104˚F/35˚C to 40˚C).

• Do not expose the projector to moisture, dust, or

smoke. This will harm the screen image.

• Ensure that you have adequate ventilation around your

projector so heat can dissipate. Do not cover the vents

on the side or the front of the projector.

Reflecting the Image

Using a mirror to reflect your projector’s image enables

you to enjoy a much larger image when a smaller space

is required. Contact your NEC dealer if you need a mirror

system. If you're using a mirror system and your image

is inverted, use the MENU and SELECT buttons on your

projector cabinet or your remote control to correct the

orientation. (→ page 45)
